Re: [Chevelle-list] SB lifter question
Luckily it's not like I keep adjusting it and it keeps getting worse. It's more like I developed a tap and now I can't adjust it properly. Hoping for the best. Thanks everyone for the good suggestions. Quoting Jim Thompson : Sorry to bring this up. You may have a wiped cam shaft. The cam lobe has worn, you adjust lifter the cam wears down more you adjust lifter. See the cycle. You need a dial gauge to check the lift before installing new lifters. Jim

Thanks. That is a good point and a good thing to check for.

Re: [Chevelle-list] SB lifter question
Thanks Tom. Of course I'm hoping it's not the cam but it seems like the lifter is not holding pressure. Hoping for the best. I'm going to tear it down on Thursday.

Re: [Chevelle-list] SB lifter question
Good call on the oil. Fort us with old cars and anything other than roller lifters, make sure you buy and oil that is Diesel certified CJ-4 for the best protection and no need for extra additives.
